A salometer and flow rate sensor assembly for a water softener system including a brine tank containing a brine solution including at least one sensor housing provided in the brine tank, a first detector set associated with the housing and configured for indicating whether the brine solution is adequately concentrated and a second detector set associated with the housing and configured for measuring the brine solution flow rate during brine draw and refill cycles of regeneration.

Salometer and flow rate sensor assembly

A grey water treatment system for use in conjunction with a water softener, including a grey water holding tank including a first inlet configured to receive grey water and a second inlet configured to receive spent brine from the water softener. The spent brine is mixed with the grey water in the holding tank to flocculate suspended solids in the grey water for subsequent removal.

Grey water treatment system

A fluid treatment system includes at least one flow-through tank, a treatment device configured for treating at least one of an untreated fluid and a treated fluid and providing the treated fluid to the at least one flow-through tank and at least one sensing device configured for sensing the quality of fluid in the at least one flow-through tank. The sensing device is connected to the treatment device for providing the treated fluid to the at least one flow-through tank upon a determination of a quality of fluids in the at least one flow-through tank being less than or equal to a predetermined fluid quality threshold.

Flow-through tank for water treatment

A process and apparatus for membrane treatment of a feed liquid to form a product liquid includes feeding a feed liquid, typically an aqueous solution such as tap water, to a primary membrane. The primary membrane separates the feed liquid into a primary membrane retentate which is retained by the primary membrane, and a primary membrane permeate. The primary membrane retentate is then fed to one or more supplemental primary membranes, or to a secondary membrane. The primary membrane retentate (or supplemental primary membrane retentate if a supplemental primary membrane is employed) is separated by the secondary membrane into a secondary membrane retentate which is retained by the secondary membrane, and a secondary membrane permeate passes through the secondary membrane. The secondary membrane retentate may either be collected and disposed of, or may be fed to one or more supplemental secondary membranes. If the secondary membrane retentate is fed to a supplemental secondary membrane, the secondary membrane retentate (or retentate from a prior supplemental secondary membrane) is separated into a supplemental secondary membrane retentate and supplemental secondary membrane permeate. The final product liquid is formed by blending the primary membrane permeate with the secondary membrane permeate and, if applicable, all supplemental primary membrane permeates and supplemental secondary membrane permeates.

Process and apparatus for blending product liquid from different TFC membranes

An improved method for regenerating ion exchange resin in a treatment tank having a flow direction, which includes the steps of providing a supply of regenerant under pressure into the tank, and introducing the regenerant into the tank in an opposite flow direction to the treatment flow direction. In the preferred embodiment, the regenerant is a combination of CO which is mixed with water to form carbonic acid and citric acid. This mixture is then introduced into the treatment tank without storage.
